Description

Technical Field

[0001] The utility model relates to the technical field of laser positioning, and specifically relates to a three-dimensional space positioning device based on laser positioning. Background Technique

[0002] Laser positioning is a technology that uses laser beams for precise positioning. Its principle is to emit a laser beam between the measured object and the sensor, and generate a detectable point or laser stripe on the object. After the sensor receives the reflected laser signal, according to the time delay and spatial relationship of the signal, the precise position of the object is calculated. A laser positioning system usually consists of a laser emitter, a sensor, and a computing device. The laser emitter generates a narrow laser beam and focuses it on a very small point. When the laser beam irradiates the object, it will generate a scattering point or laser stripe on the object surface. The sensor converts the received scattering signal into an electrical signal and processes it through the computing device. In the computing device, according to the time delay of the received laser signal and its position information on the sensor, the three-dimensional position coordinates of the object can be calculated. Laser positioning technology has the characteristics of high precision, high speed, and non-contact. Due to the small scattering characteristics of the laser beam, it can achieve the positioning and measurement of small objects. In addition, the laser positioning system can also analyze the trajectory of the laser beam to achieve the recognition and tracking of the object shape and motion state, and is widely used in industrial automation, robot navigation, three-dimensional reconstruction and other fields.

[0003] When laser positioning is required, a positioning device is needed. The existing positioning devices cannot quickly position the object to be measured, resulting in reduced use efficiency for users. Therefore, we provide a three-dimensional space positioning device based on laser positioning. Content of the Utility Model
